PUMP.

Application led October 13, 1921. Serial No. 507,435.

To all whom if may concern:

Be it known that I, GEORGE S. EDER, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Pumps, of which the following is a specification.

This invention appertains to certain'improvements in pumps generally, and more particularly to a type thereof adapted for use in pumping out the contents of gas and oil barrels, containers, and the like.

The principal object of the invention is to provide for a pump of the class mentioned, and one of an extremely simple, durable, and efficient construction, arrangement, and operation of parts, such as is capable of being manufactured at a minlmum and comparatively low cost,and which is readily and easily installed in operative position, or removed therefrom, and otherwise manipulated for its intended purposes.

With the foregoing and other objects in view, the invention resides in the certain novel and useful construction, arrangement and operation of the parts thereof as will be hereinafter more fully described, set forth in the appended claims, and illustrated in the accompanying drawing, in Which:-

Figure 1 is a side elevation, partly in section, of a preferred embodiment of the Pump,

Figure 2 is a horizontal section taken on the line 2 2 of Fig. 1, i

Figure 3 is a plan View of the removable head slot or cap per se of the pump cylinder, and,

Figure 4 is a horizontal s the line 4-4 of Fig. 1.

Referring to the drawing, the numeral 10 indicates an open ended cylinder having its v lower end seated within an annulus 11 formed in a valve casting 12, and its upper end normally closed by means of a head block or cap 13 which is clamped in position, together with the cylinder 10 and the ection taken on valve casting 12, by means of bolts 14 which are passed downwardly through openings formed in a flanged portion 15, of the head or cap 13,-and similarly formed aligning openings formed in a flanged port-ion 16 of the valve casting 12. Mounted Within the cylinder l() and projecting upwardly and concentrically of the head block or cap 13 is a piston rod 17 having its upper end por- Vallel relation at one side tion formed to provide an enlargement 18, arranged to function as a stopfor limiting the downward reciprocating movement of the piston, and the extremefree end of the end portion is bifurcated to provide a pair of spaced ears 19 immediately above the enlargement 18. An operating hand lever -20 is pivoted, by means of a pivot pin 21, between the ears 19 of the piston rod 17, and 1s further pivoted, by means of a pivot pin 22, between a pair of ears 23 formed at the upper end of a fulcrum bar or rod 24, which, 1n turn, is pivoted atits lower end on a pivot pin 25 extending between a pair of ears 26 projecting outwardly in spaced parof the upper face ofthe head block or cap 13. Mounted on the lower end of the iston rod 17 are a pair of annular clamp col ars 27 and 28, between -the opposed faces of which are positioned a pair of pump leathers or the like 29 and 30, which are cupped in opposite directions and correspondingly fitted over the collars 27 and 28, respectively. rlhe inner ofthe collars 27 is arranged in abutting relation to an lenlargement 31 formed inwardly of the lower end of the piston rod 17, while the outer end face of the outer of the collars 28 is abutted against clamp nut 32 which is threaded onto the free end of the piston rod 17, whereby to effect the securing of the collars 27 and 28 in position for the clamping of the cupped leathers 29 and 30 therebetween.

The valve casting, designated generally at 12, comprises an enlarged inlet valve portion 33, and an ,angularly offset and upwardly curving outlet portion 34, the up er open side of the inlet portion 33 being,

formed to provide the annulus 11 for the seating therein of the lower end of the pump cylinder 10, while the lower side of the same is provided with a cylindrical eX- tension or nipple 35i having a threaded bore therein for the connection thereto of a suitable length of pump tubing '36, which bore is of a less diameter than that of the interior of the portion 33, or of the upper opening thereof. Fitted Within the bore of the extension or nipple 35, immediately above the inwardly threaded end of the tubing 36,

is a valve seat 37 for supporting thereon a ball valve 38, the upward movement of which, during the upward or suction stroke of the piston 17, is limited by means of an annular guard 39 which is seated in 'the l annulus 11 beneath the connected end of the o linder and has a crossfbar 40 dispose diametrically thereof and in the path of the ball valve 38 in its opening movement from the seat 37. The free end of .the upwardl Lcurved portion of the outlet portion 3420 thevalve casting 12 has fitted into the bore thereofa valve seat 41 sup'- porting infposition' thereon of'an outlet ball valVe42, which is enclose'dlwithin @a casing 43 threaded onto and exteriorly of the free tically extendin end portion 34, and this casing has an 'out-\ let nipple or extension 44 whlch has lts bore 15 threaded to receive the lower end of a verdischarge pipe or tube section 45,"whic in turn, has its upper end threaded to receive thereon an L-coupling 46 0r the like for the connecting to the same of a downwardly and forwardly curving discharge hoseor spout 47.

' For adapting the pump for use in draw'- ing off thecontentsof barrels, containers or the like, the. tubing 36 is 'to be inserted into .the usual bung hole of a barrel, (notshown), and is supported in operative position 1n a clamp member which is formed in two sections 48. and 49, the former. provided with a llateral ear 48 and the latter with the pair of spaced lateral ears 49', between which .ex-

. tendsthe ear 48. The ears 48', 49 are pivv clamped around the tubing36 at the required v Aat oted together as at 50, and which areto be distance upward from the lower end thereof to admit of the latter end extending 1nto the 'barrel and in contact with the bottom wall thereof, the parts or sections-48 and 49 being rovided With a fastening means, preferably 1n the form of a bolt 51 passed through a pair Oflateral extensions 51 formed thereon. at the side of the same opposite to the -point .of pivotal connection thereof one wlth the othei. The bolt 51 is 'disposed at right angles with respect to pivot 50. The sections 48 and 49V are each formed with complemental lower threaded portions 52 and complemental intermediate threadedportions 53'of ga'greater diameter than the 52, whereby tol adapt the sup or t for threaded engagement in bung ho esv -of differentower portion sizes, and by adjusting the clampl member i vertically on the tubing, the latter may be elo led

Y sai vregulated correspondingl for insertioninto barrels or containers of different depths.

j In thel operation of the pump, the usual bung of a barrel, cask or the like, (not shown).

is removed,'and the tubing 36 inserted into the opening thereof to a proper depth to assure of the entire drawing oifv of the contents ofthe same, and is supported in position by either one or the other of the threadortions 52, 53, being. screwed into the bung opening, the cast member being adjusted' vertically on the tubing for the purpose. When it is des-ired'to draw "off the contents of the barrel or container, the handle 20 is grasped in theusua-l manner and v moved up and down for'the'purpose o'fre- Iciproczating the piston :17, on-the upward'- stroke of which, the ball valve 38 will bel lifted from its seat 37 and a portion of the contents of the-barrel or container drawn into the cylinder 10, during which operation,

the ball Vvalve 42 'will be held on its seat 41 by the suction created by the piston. On the down stroke of the piston 17, the ball valve close all communication between the container and the pump cylinder 10, andthe contents of the latter forced outward through thev outlet portion 34 of the valve 38 will be forced back onto its seat 37 tu casting 12, where it will lift the ball valve 42 from its 'seat 41 andpass .through the casing 43 into the tube 45 and discharge vfrom the hose or spout 47. During s'uccessive reciprocations of the piston 17, this opv eration will be repeated as long as desired or until the container has.. been completely atv54, and preferably on a. line diagonally upward at one side of the same to provide a vertically elongated openin', whereby to facilitate the drawing ofi' of a l of the usable contents of the barrel or container without affecting the drawin oil' of any dregs 0r sediment which may ave been precipitated" to the bottom thereof, when-the tube v36l has its lower end resting on the 4bottom wall of a barrel or other container and the opening is of a. length ,to have its upperend disposed above the' level of the dregs or sediment4 for the purpose leading outwardly and downwardly from the `cylinder' 1l),l from a point above the limit` of the upward stroke .of the piston, is-a drain pipe 55 through which any and all of the liquid, bein pumped and seeping past the piston hear?, will be returned to the barrel or `other container, the lower end of the same being pro.- jected into the latter for such purpose, or otherwise arranged to discharge suchover flow liquid therein, or into any other separate container as may be desired or necessary.

From the foregoing, it will ,be vreadilyapparent that, while a preferred embodiment of the -pump has been' described Tand illustrated herein in specific terms and details of construction, arrangement', and operation, various changes vin v and modifications of the same may be resorted to without departing from the spirit of the invention,y or the scope of the claims appended hereto.
